In this program, we are going to share a C++ program to optimize wire length in electrical circuit. If you are a C++ beginner and want to learn C++ programming, then keep your close attention in this tutorial as I am going to share a C++ program to optimize wire length in electrical circuit with the output.
Copy below C++ program and execute it with Turbo C compiler to see the output of the program.
